A great place to start in Scandinavian decor is with your textures. Since there isn’t a lot of extra to see in the way of decor, it‘s a great help to have linens and different types of weaves. Add a jute rug under the coffee table. Toss a sweater-like throw blanket on the couch. Add a chair with a linen weave.
As a beautifully balanced cross between, or combination of, green and blue, teal itself is a magical color that feels simultaneously soothing and energetic. Deep teal showcases that same sort of energy, but as a darker shade, it feels a bit more sophisticated and reigned in. For the living room that wants to be warm and welcoming but not in-your-face or peppy, deep teal is an excellent color choice.
Whether you have a country decorating bent or not, a piece or two featuring rustic wood is a great way to stay neutral and be natural at the same time. You can buy a piece of furniture or even DIY something like a sign but it will definitely aid your Scandinavian decor goal.
